fully described though not claimed. The

invention relates to apparatus for making receptacles and has special reference to the manufacture of suit cases and like containers, preferably of paper, cloth, leather, etc., or various combinations of same.

The principal object is to make a more durable and serviceable receptacle of this character than is customary.

Another object is to provide a novel means and method whereby such a receptacle may i be more cheaply and easily made than heretofore.

' Still another object is to provide simple and practical means for making a receptacle having evenly formed rounded. corners both internally and externally, this being for both durability and appearance.

Another object is to provide an adjustable form upon which the initial steps are performed in making such a receptacle.

-Other objects and advantages of the in vention will appear in the further description thereof.

Referring to the accompanying drawings representing one practical embodiment of the invention and in which like reference characters indicate like parts:

Fig. l is a perspective view of one of the moulding receptacles in semi-opened position.

Fig. 2 is a central transverse sectional view throu'gh the closed mould having enclosed both portions of a suit case under construction and the expansive bag.

Fig. 3 is a plan view of one corner of the intermediate section of the mould and a transverse sectional view of same.

Fig. 4 is an under plan view of the expansible block upon which the sections of the suitcase or other receptacle being made is formed.

Fig. 5 block.

Fig. 6 is a plan of the plain bloclcsupporting spider,

Fig. 7 is a vertical sectional view of the air and water supply connection to the expansive bag,

Fig. 8 is a vertical section through the center of the expanding spider showing the two blocks on the far side of the center in elevation.

1 represents the main body portion of the mould in which the like half of the receptacle to be made is eventually formed, and 2 represents the cooperative cover-holding portion, while 3 represents the intermediary section of the mould which is installed between the two main sections for forming the contracted marginal edge of the main body portion of the receptacle such as a suit case is a side elevation of the forming body as it is being formed.

The intermediate section 3 has formed upon its opposite upper and lower faces extending ribs or tongues 4 which are engaged within cooperative grooves formed about the engaging edges of the portions 1 and 2 of the'mould the same being for the purpose of providing a positive and tight joint intermediate of the engaging portions of the re ceptacle. Said section 3 extends somewhat within the interior of the forming receptacle when assembled, said extension being inclined as at 5 to form an inwardly inclined or contracted marginal edge on the body portion 6 of the receptacle being formed as clearly illustrated at 7, Fig. 2-, while the marginal edge of the cover portion 8 of the receptacle being formed abuts against the shoulder 9 of the section 3 when within the mould. I

I have shown the cover and body portion of the mould as being united upon one side by hinges indicated at 10 and which may be of any desired form for the purpose, the opposite side of the two sections having means for clamping and holding them securely together such as cooperative pairs of lugs 11 on the cover section and 12 on the body section, the latter pivotally carrying bolts 13 having thumb nuts 14% carried upon their extreme ends which will engage the upper faces of the lugs 11 when the bolts are swung into position for clamping the sections of the mould together, it being under-= e stood that the hinges 10 are so applied to the sections of the mould as to provide space for the insertion of the intermediary section 3.

The expansive bag is indicated at 15 and is of the proper size and form to readily fit within the mould after the receptacle being. formed isplaced therein where it is securely confined by the assembling of the mould. A rectangular shaped hole 16 is formed centrally of the front wall of the body portion 1 of the mould and through which the pipe connection 17 to the expansion bag 15 may be inserted and screw threadedly attached to the bag which is pro vided with a registering hole having a suitable bushing 18 therein for the purpose, or if preferred the pipe connection 17 maybe applied to the bag prior to the latter belng positioned within the mould as being of soft. and flexible structure the bag may be readily squeezed together to permit of the pipe connection or nipple 17 being extended through the opening 16 from the interior thereof and which preferred structure 18 shown in Fig. 7 of the drawings.

In the embodiment here illustrated in Fig. 7 I have shown a short piece of tubing 19 attached to the central inwardly extending nipple portion 20 of the pipe connection 17, the office of which will be described later.

The bag 15 is made of any suitable rubber composition as indestructible as possible and capable of the necessary expansion for the purpose, it being found from practice that such should have walls of considerable thickness and shaped as near to the internal measurements of formed as practical.

I have shown in Figs. l, 5, 6 and 8 a convenient form upon which thesections of the receptacle being made are initially shaped, the same comprising four light substantially rectangularly shaped skeleton or hollow blocks 21, they being positioned to form a square and thus expandably held by the flat metal spider. the body of which is illustrated at 22 and the diagonally extenrb inc; arms at 23. The under face of each block is provided with straps 24 or other suitable means fixed thereto for slidable engagement with the arms 23 otthe spider, and said arms being disposed at an angle of 45 degrees to the body portion 22 of the spider will govern the movement of each block only at such angle.

Fined centrally of and depending from the body portion 2-2 of the spider is a pin or supporting member which rotatably carries thereupon a disc 26havingri a handle 27 extending radially therefrom and four areuaately shaped slots 28 therein, the outermostend. of each one of said slots opening the receptacle 'loeing through theperipheral edge" of the disc and.

enggarnnegi a downwardly protmding pin 29 rigidly fixed to the innermost strap 24 u on each block 21. By this arrangement wien the disk is rotated in one direction all of the blocks will be simultaneously moved from each other or 'adially from the center of the disk while when the latter is moved in the opposite direction they will be drawn towards each other as is obvious.

Below the disk 26 and screw-threadedly mounted upon the pin 25 is a hand nut 30 which may be adjusted to impinge the disk 26 for holding it locked in any desired posi tion in relation to that of the blocks.

As a preferred form of support for the pin 25, I have shown it pivotally mounted within a normally horizontally disposed pivoted member 31 which is supported by an upright member 32 designed to be bolted to the table or work bench made use of in the employment of the device. This form of supportpermit's of convenient manipulation of the device when being used.

Both the cover and body portions of the receptacle may be made or shaped upon this adjustable form the blocks are provided with a recess as at 33 for the reception of the reinforcing metal band used in strengtlr eninp; the edges of the cover 8 of the recepta ole, the same being. incorporated within the material of which the cover is composed and the blocks are also provided with a suitable recess or groove 34 for the reception of the wire reinforcement which is incorporated in the marginal edge of the body por tion 6 of the receptacle being formed, it also being; incorporated within the material of which the receptacle is formed. This incorporation of the reinforcing members is accomplished by first placing, strips of cloth, leather or paper. as the case may be, over the channels or grooves in the blocks before the reinforcing: members are ,applied thereto. thus permitting of said strips being wrapped about the members andv incorporated with the succeeding strips or pieces of which the receptacle is composed, this being preferably accomplished by alternate layers of suitable material such as paper, cloth.;wire netting and the like commonly usedin theconstruction of such receptacles and which are glued or pasted together forming: a concrete structure which may be subsequently softened by heat andpermanently fixed or set duringthe further process of shaping in the mould, previously described.

It is evident that when the different sections of the receptacle arebuilt up in this manner upon the form, the blocks" may :be drawn toe'ether by proper manipulation of the disk26 andthe sections readily removed therefrom and in fact any desired tension or manipulation of the blocks may be readily accomplished to assist in, the process of building up the. sectionsthereuponh Then each pair of sections prepared in this ;,n:1an

ner is placed within the mould for final shaping as shown in Fig. 2 with the expansion bag therein and the pipe 17 extending beyond the mould, said pipe being provided with the inwardly protruding nipple 20 forn'iing communication with the pipe 19, as above d cscribed. About the nipple 20 and in the main body portion of the pipe 17 is formed a plurality of holes or passageways extending longitudinally the pipe and spaced from the central here or passageway 35, thus providing separate channels of communication to the interior of the expansive bag, this specific structure being shown in Fig. 7 of the drawings.

As a convenient means for supply elements to the pipe 17 1'. have shown a hand nut 36 engaged in any desired manner back of the shoulder 37 adjacent the inner end of the pipe 39 whereby the nut may be turned :lt'or engaging the cooperatively screw threaded end 38 of the pipe 17 without becoming disengaged from the end of the pipe 39. The pipe thus terms an extension of the pipe 17 it being provided with the same number and arrangement of passageways therein which register with-the passageways 44 and 85 in the pipe 17. Upon the outer end of the extension 39 is screw threadedly mounted a T coupling 40 having the supply pipe 41 screw threadedly engaged in the 0pposite end thereof, said pipes 39 and 41 having reduced central nipples similar to the nipple 20 on the pipe 17 and which abut each other within the T 40, thus forming a continuous passageway through said T when the pipes are screwed tightly together in the T and leaving a space about the abutting nipples which communicates with the passageways 44 in the pipe 39. Into the lateral connection of the T is screw threadedly at tached a supply pipe connection 42 having any Form oi? suitable relief or safety valve 43 installed therein to prevent abnormal pressure within the expansive bag and which valve may be set for certain predetermined pressures as is commonly practiced in such devices, the same forming no part of my present invention. In this manner I am enabled to supply two different elements to the interior of the expansive bag it being understood that the pipes 41 and 42 will be provided with suitable controlling valves not shown.

Tn Fig. 2 l have shown a modified form of supply connection to the interior of the bag and wherein but a single element may be supplied thereto as in the final shaping and fixing of some forms of material but asingle element may be necessary, as for example, air, while in the attachment shown in Fig. 7 it is designed to use both air and water, the latter being introduced through the pipe 41 and the former through the pipe 42. In this event hot water is first introduced into the bag to warm and soften the adhesive-substance used in the building up of: the receptacle parts when they were shaped upon the form and after this has been accomplished. to suflicient extent the water connection with the interior of the bag is opened and air is supplied under pressure to the pipe 42 thus -forcing all of the water from the interior of the bag and herein appears the necessity of the bent pipe 19, the lower end of which is designed to terminate close to the bottom of the bag so as to readily remove all water therefrom to permit of the air thoroughly drying out the latter and concluding the final forming of the receptacle, and the pressure within the bag, the air being heated or not as practice may prove essential.

After sufficient heating has taken 'place by this means pressure may be maintained within the bag while the material of which the receptacle is formed is becoming permanently set, thus concluding the final forming thereof.

It is to be understood that various modifications and changes in the specific structure here shown may be resorted to without departing from the spirit of the invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is o 1. The combination with an adjustable, receptacle forming block, comprising a plurality of simultaneously movable parts, of recesses within the outermost walls of the parts for the reception of reinforcing bands or rings whereby they may be incorporated within the receptacle formed upon the block.

2. A rectangularly shaped adjustable block of the character described comprising four rectangularly shaped equal parts, a spider comprising a flat elongated bodv portion, arms formed integral with and extending diagonally from said body portion, means for slidably carrying each one of the blocks upon one or more of said arms, a rotative member pivotally carried centrally upon the body portion of the spider, arcuately shaped slots within the rotative member and a pin rigidly carried by each of the parts cooperatively engageable within one of the slots in the rotative member whereby when the rotative member is actuated the parts of the block will be simultaneously adjusted.

In testimony whereof I hereunto alfix my signature in the presence of two witnesses.
